  1. March 12, 2019 Live ‐ Donor Liver Transplantation: A Life ‐ Saving Option for End ‐ Stage Liver Disease Abhi Humar, MD Clinical Director, Thomas E. Starzl Transplantation Institute 1 PITTSBURGH—THE BIRTHPLACE OF LIVER TRANSPLANTATION  Liver transplantation: one of the miracles of modern medicine  Liver transplant is now established as the only definitive treatment for end‐stage liver disease (ESLD)  Survival following liver transplant  1 year survival: 87 – 93%  5 year survival: > 75% 2 1

  2. March 12, 2019 LIVER TRANSPLANTATION AT UPMC: AN ESTABLISHED LEGACY Dr. Starzl performs Pittsburgh’s first liver transplant, 1981 establishing the country’s first liver transplant program. 1985 Over 600 liver transplants performed in a single year. Tacrolimus introduced as the new immunosuppressant 1989 drug. 1999 UPMC performs its first adult living‐donor liver transplant. 2017 UPMC performs more living‐donor liver transplants than deceased donor liver transplants. UPMC and Pitt establish the Immune Transplant and 2018 Therapy Center, which will work to reduce immunosuppressants. 3 CURRENT STATUS OF LIVER TRANSPLANT IN THE U.S. Living Donor tx Waiting List 18,000 Series2 Deceased donor tx Series3 Series1 16,000 14,000 12,000 10,000 8,000 6,000 4,000 2,000 0 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 4 2

  3. March 12, 2019 CONSEQUENCES OF A WAITING LIST AND LIMITED RESOURCE What does this mean for the individual patient needing a liver transplant? 1. About a 15‐25% chance of never making it to transplant 2. Longer waiting times before receiving a transplant • A more debilitated state by the time a transplant is performed • A longer and more difficult recovery time post‐transplant 3. Not all patients that could benefit are listed or offered transplant 5 PROBLEM: NOT ENOUGH LIVERS FOR ALL THE PEOPLE WHO NEED THEM Median Waiting Time PAPT Mean MELD 30 Deceased Donor 35 25 30 20 25 20 15 15 10 10 5 5 0 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 0 2012 2013 2014 2015 2016 2017 PAPT MEAN MELD ‐ DECEASED DONOR Linear (PAPT MEAN MELD ‐ DECEASED DONOR) Patients in our local area are waiting longer and are sicker by the time they receive a transplant. Waitlist mortality of 25%. 6 3

  4. March 12, 2019 LDLT—A POSSIBLE SOLUTION FOR THE WAITING LIST PROBLEM Possible because of 2 unique properties of our liver: • Extra capacity built in • Ability to regenerate 7 ADVANTAGES AND DISADVANTAGES OF LDLTX Advantages Disadvantages • Decrease waitlist mortality • • Short‐term risks to donor Decreased waiting time • • Long‐term risks to donor Transplant prior to recipient • Increased incidence of biliary and becoming critically ill • vascular complications Elective, non‐emergent • • Decreased hepatic reserve Minimal cold ischemia • Immunologic advantage • Adds to cadaver pool • Financial benefit 8 4

  6. March 12, 2019 UPMC Living Donor Utilization/Cost Comparison  Cost of transplant (from 6 months pretransplant to 1 year posttransplant) was 30.8% cheaper in LDLT group (p<0.01)  Waitlist patients had an average of 2.7admissions/year to hospital with charges for each hospital stay averaging $70k. 11 UPMC Living Donor Utilization/Cost Comparison UPMC data shows cost benefits for living donors related to pre‐transplant radiology and post‐transplant radiology, ED visits, GI procedures and surgeries, and labs.

  13. March 12, 2019 DONOR SAFETY AND RECOVERY IS KEY  Recovery:  5‐7 days in hospital  4‐6 weeks desk job  10‐12 weeks physical job  80‐90% by 3 months post donation 25 Live donor kidney transplant is the gold standard treatment for ESRD • Between 1999 and 2011 there were 25 kidney donor deaths within 3 months of donation. • There is a very slight increase in risk for developing ESRD over time in kidney donors • No cases of late liver failure reported after liver donation 13
